M contained 4 ingredients. The other 3 were (taken from M literature):
Trihydroxystilbene blocks estrogen at the actual receptor site in male breast tissue and other estrogen-sensitive tissues.
Tocotrienols work synergistically with estrogen blockers to dramatically increase the overall effect at the receptor, as well as through non-receptor mechanisms.
Calcium D-glucarate clears excess estrogen from the body by inhibiting the enzyme that's responsible for the activation of bound estrogen.
It seemed like a really comprehensive formula, that cannot compare with just using Vitex agnus castus, especially with the Trihydroxystilbene in there.
I have read a lot on this site of the dangers of too much estrogen in the body, especially in regards to prostrate health. It seemed like M was really an excellent stand alone product that many T-men in this plasticized world would want to use. I sure would like to see it brought back.
